SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 236,391, dated January 4, 1881.

Application filed J uue 5, 1880.

To all whom it may concern Be it known that we, ELI VANCIL, BEN- JAMIN B. BAsT, and JOHN A. HORRELL, of Jackson, in the county of Cape Girardeau and State of Missouri, have invented certain new and useful Improvements in Spark-Arresters; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

The drawing is a representation of a vertical section of our spark-arrester.

The nature of our invention relates to spark and cinder arresters; and itconsists in the features of construction and arrangement ofparts, as fully set forth in the accompanying description, and particularly pointed out in the claim.

Referring to the drawing, A represents an inverted cone shaped shell, which is formed with an annular collar, a, at its lower end, and formed at its upper end with an annular collar or flange, a. \Vithin the shell A is arranged a funnel, B, which is covered at its top with wire-gauze or perforated sheet metal. This foraminous top may be somewhat coneshaped, thus giving greater surface to the same.

0 is an inverted funnel-sha ped top or cap, having at its upper end a. foraminous short. cylindrical pipe, 1). which extends above the cap, and also extends down a short distance into the inverted funnel U. The inverted funnelshaped cap is hinged to the collar a of the inverted cone-shaped body A, and when closed down thereon is held by a spring-clasp, E.

The device is fitted to the stack, and the funnel B is held in place within the body A by rods F, secured to the funnel and passed out through the body A, nuts G being arranged upon their outer ends and tightened up against the exterior of the body A. The area within this spark-arrester is greater than the area of the stack, and the arrangement of parts efiectively stops the cinders from passing out the top of the cap. The funnel in the body A arrests a majority of the sparks and (N0 model.)

cinders. Part of the balance strike against the under side of the cap and are arrested, or in passing up along said under side of the cap will be arrested by that part of the foraminous tube which extends down into the said funnel-shaped cap. Such sparks or cinders as may pass up through the foraminous pipe will be arrested by that portion of the tube which extends above the cap, since any current of air will blow the smoke and products of combustion through the perforations of such pipe.

We are aware that a flaring or bell-shaped smoke-stack has been provided with a cylindrical screen surmounted by a hollow inverted conic sect-ion closed at the top and made of impert'orate metal; also, that a spark-arrester consisting of a vertical screen-cylinder at the mouth of the stack, through or under the sides of which the products of combustion must escape, has been used, as shown in the Patent No. 215,643 of August 19, 1879; but in this instance the vertical screeu-cylimler at the mouth of the stack does not project above the cap or mouth of the stack, as in ours. An inner imperforate casing having a perforate top and an internal deflector has been placed in a flaring smoke-stack, as shown in Patent No. 63,41 L of April2, 1867. We, however, make no claim to either of these constructions.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

ln a spark-arrester, the combination of the shell A and cap 0, incasing the funnel B, provided with a perforate conical top, with the vertical cylindrical screen D, extended both above and below the mouth of the cap 0, substantially as and for the purposes set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
